k0rdent is an open-source platform designed to deploy and manage Kubernetes clusters at scale, functioning as a "super control plane" that orchestrates multiple Kubernetes control planes seamlessly. The project positions itself as a comprehensive solution for Platform Engineering, enabling organizations to build Internal Developer Platforms, implement centralized cluster management, and establish Golden Paths for consistent development practices across on-premises, cloud, and hybrid environments.
The architecture follows a declarative approach using Kubernetes Cluster API principles, where users define desired cluster state in YAML and apply it to a management cluster. This management cluster orchestrates provisioning and lifecycle management of multiple child clusters without requiring direct interaction with individual infrastructure providers. The declarative model enables cluster definitions to be largely reusable across different cloud environments like AWS and Azure. The architecture encompasses cluster management tools and controllers, state management systems for monitoring and updating child clusters and workloads, infrastructure providers for provisioning resources, and templates for defining managed clusters and their workloads.
Installation involves creating a management cluster, installing k0rdent into it, and configuring necessary credentials and templates for infrastructure providers. The project provides both a QuickStart Guide and a comprehensive Administrator's Guide to Installation, with full documentation available at docs.k0rdent.io.
